Critically ill patients frequently have compromised respiratory and hemodynamic function. Chest physical therapy has been previously shown to increase oxygen demand and therefore was used to examine how postoperative mechanically ventilated patients responded to an increased oxygen demand. We found that during chest physical therapy, oxygen consumption increased 52% +/- 37% (SD) over baseline values. There was a 35% +/- 32% increase in oxygen extraction and a 17% +/- 33% increase in oxygen… CONTINUE READING
